stumps, and pools. In these places the water is often yellow 

 with impurities. The wigglers live on the bits of matter that 

 are in the water. 



2o THE PUPA 



Among the wigglers you may see a few that are 

 different in shape, and that swim with their bodies in 

 a different position from 

 the others. These are in 

 the third stage of the life 

 of a mosquito, and are 

 called piqjas. 



Observation. — What is 

 the shape of a mosquito 

 pupa ? What is its color ? 

 When it is still, does it 

 rest with its head or its 

 tail downward ? While it 

 is at rest what part of its 



body touches the surface of the water ? Where are 

 its breathing tubes? What parts of a full-grown 

 mosquito do you see in the pupa? Do you find 

 some empty wigglers' skins in the water with the 

 pupas ? In what part of the water are the skins ? 



Drawing and Composition. — Draw a picture of the 

 pupa of a mosquito three or four times as large as 

 a pupa is. Write a short paragraph describing the 

 pupa, and another paragraph telling what the pupa 

 did while you looked at it.
